Benefits of Coffee

“I need coffee.” It’s a phrase most of us utter (or hear) every single day.

In the U.S. alone, 80 percent of adults consume some form of caffeine daily. Obviously we’re obsessed—with coffee, in particular. And it’s not just the dark, roasted flavor, or the rich and robust aroma—it’s that undeniable feeling of sipping your way to a state of alertness and focus. There’s nothing better. Drinking it is a morning ritual for so many people. And it’s always there—brewing nonstop in office kitchens, waiting rooms, and of course, cafes on every corner.

It’s so ubiquitous that we’ve come to take it for granted. But the world’s favorite beverage actually has a LOT to offer in terms of health benefits—it’s full of essential phytochemicals and antioxidants.

Benefits of coffee

Check out some of the amazing things coffee can do for you and your body.

Increased energy levels

The No. 1 advantage to drinking java is of course getting that jolt of energy. According to the USDA, one 8-ounce cup of joe has about 95 milligrams of caffeine—more than most other sources, including tea, soda, and chocolate. Various studies have shown that just one cup produces the desired effects, but sensitivity does vary from person to person, depending on genetics and body weight.

Optimized physical performance and better fat burning

Heading to the gym? Most people would default to hydrating with a glass of water, not coffee, which could have the opposite effect, right? Well, turns out coffee makes a pretty stellar pre-workout beverage to help you go the distance. Caffeine has shown to reduce ratings of perceived exertion—meaning, it can make intense exercise feel easier by as much as 12 percent on average. It also gets your adrenaline pumping.

Essential nutrient boost

For such a low-calorie beverage (about 2.4 calories per 8-ounce cup), coffee’s got quite a few nutrients to offer: thiamin, riboflavin, niacin, folate, magnesium, phosphorous, potassium, and manganese. While these are all present in small amounts, in a standard American diet that’s typically deficient in fruits, vegetables, and whole grains, a coffee or two every day can help close the gap.

And according to a study published in the journal Cancer Research, caffeine may protect against the most common form of skin cancer, basal cell carcinoma. The results were greater in men and women who drank more than three cups daily. But the researchers still advise against relying on coffee to offer adequate sun protection—so don’t skip the topical SPF.

Natural antidepressant properties

Most people have experienced that perked-up feeling that comes from sipping on some java. Well, it’s not all in our heads. Actually, it kind of is, in a literal sense:

So if you’re feeling down, turning to a comforting cup of joe may offer a quick pick-me-up.

Longevity

A 2012 study from the National Cancer Institute found that coffee drinkers tend to live longer than those who abstain. More recently, a study from the Harvard School of Public Health found that those who drank three to five cups daily were 15 percent less likely to pass away prematurely—although the study merely shows an association rather than cause and effect. Caffeine didn’t even seem to be much of a factor in these studies—even drinking decaf showed similar results, pointing to the power of coffee’s many phytochemicals.

Skin benefits

We pretty much know the drill when it comes to antioxidants—they fight free radicals (unpaired electrons) that accumulate in the body over time from everyday occurrences like digesting food and even breathing. (Environmental pollutants can also increase free radicals in the body.) These highly reactive, lone electrons seek to pair up with other electrons and end up scavenging them from other molecules, causing cell damage, which can lead to accelerated aging (not to mention cancer and other diseases).

“Antioxidants neutralize free radicals either by providing the extra electron needed to make the pair, or by breaking down the free radical molecule to render it harmless.” —Solmaz Barazesh, Science Writer, National Academy of Sciences

Antioxidants have become lauded as one of the keys to anti-aging skin care. And it turns out most people get a majority of their antioxidants from coffee, rather than other sources such as vegetables and fruits. While we do recommend a diet rich in fresh produce, it’s nice to know that an espresso habit may help boost the skin’s radiance and elasticity.

Risks and disadvantages of coffee

Just like most things that are good for us, coffee’s rewards may come with a few risks.

Increased tolerance and dependency

It seems that many of the benefits of coffee are amplified by drinking more of it. However, it’s possible to develop a tolerance, which can lead to binge drinking (of lattes, that is). Be careful not to exceed 10 grams of caffeine (that’s 75 8-ounce cups within a few hours), which is considered the toxic level in humans. (Okay, that’s a lot, but the more you know…)

Another reason to keep an eye on your intake—you could develop a mild physical dependency on it. Both tolerance and dependency are not only bad for the bank account (hey, those $4-and-up takeout cups ain’t cheap), but also make it easier to fall in love with the local cafe’s sweet offerings, which are nothing more than sugar- and calorie-bombs.

Caffeine withdrawals

As with any “addiction,” quitting or cutting back on caffeine abruptly may bring about symptoms of withdrawal, including:

Headache

Fatigue

Sleepiness/drowsiness

Difficulty concentrating

Difficulty working

Irritability

Depression

Anxiety

Flu-like symptoms

Impairment in psychomotor, vigilance, and cognitive performances

Insomnia and anxiety

We know that coffee is powerful stuff, so it’s no surprise that it can alter physiological states in the body. Caffeinating before bed may keep you awake at night by inhibiting the way adenosine, a molecule that helps your body go to sleep, works in the body. This reaction can also trigger the all-too-familiar jitters. James Lane, a researcher out of Duke University, noted the link between caffeine and stress:

“ … caffeine always exaggerates the effects of whatever stresses we are currently experiencing in everyday life. It is curious that people often turn to coffee in times of stress, like deadline pressure. The caffeine makes the deadline more stressful.”

Pay attention to your body and give yourself a coffee cut-off time—a good rule of thumb is to refrain from drinking it six hours before sleepy time. And If you’re going through something hectic, it might be a good idea to cool it on the coffee.

Heart risks

Drinking unfiltered coffee (i.e. brewed in a French press) may raise the bad cholesterol, LDL. But caffeine isn’t to blame—it’s the compound called cafestol. Luckily, it can be removed by using filters, so regular brewing processes tend to be safer. But if you love your French press, consider reserving it for special occasions.

It’s also high in omega-6 fatty acids; while these are essential, too much can raise blood pressure and lead to blood clots that can cause heart attack and stroke. It’s important to balance omega-6s with omega-3s—that’s the beauty of drinking a version of Bulletproof coffee that incorporates grass-fed butter for added omega-3s.

Diuretic effects

Stopping by a Starbucks before heading out on a road trip sounds good in theory, but it’s also going to up your number of pit stops. The diuretic nature means more frequent trips to the bathroom—for number one and two.

So, is coffee healthy? For sure! If drinking it is one of the highlights of your day—and it is for most people—then by all means, enjoy! But for those who aren’t big fans, experts don’t necessarily recommend starting just for health benefits. There’s always green tea.
